CVE-2026-85400

Backend administrators without system maintainer privileges were able to schedule any of the configuration:read, configuration:set, and configuration:show commands. This allowed them to modify arbitrary system configuration, which is normally limited to system maintainers. As a consequence, this allowed them, for example, to gain system maintainer privileges or cause a denial of service. Exploiting this vulnerability requires an administrator-level backend user account. This issue affects TYPO3 CMS versions 14.2.0-14.3.6.
